What was the original name of Rosalie?

Answer 1

Rosalie's original name was Carol. Jasper's name was Ronald and, quoting Stephanie Meyer, 'I sometimes still write Carol and Ron. It really confuses the people who read my first draft.' When Rosalie was a human she was called Rosalie Hale, but Jasper wasn't called Jasper Hale. It never actually mentions what Jasper's name was when he was human.

Answer 2

Her name was Rosalie Hale. Now she uses that name at school to keep up the idea that her and Jasper are twins that were adopted by the Cullens. She was nearly killed after being raped in the street while on her way home from her best friend's house. She was raped by her rich, but drunk fiancee and his drunken buddies. If she hadent been nearly killed and then changed, her name would have been Rosalie King, because the name of her fiancee was Royce King. To read the whole story told by Rosalie to Bella, its chapter 7(Unhappy Endings) in Eclipse.
